Аннотация
OBJECTIVE: This study summarized the clinical characteristics of X-linked adrenoleukodystrophy (X-ALD) patients in this family, and two different manifestations of the same variants in a Chinese family were reported in this article. That conducted a follow-up study to further clarify the characteristics of this disease.
BASIC METHODS: Clinical data and test results were analyzed, and the exon region of ALD-related gene ABCD1 was sequenced by Sanger sequencing.
MAIN RESULTS: Gene analysis showed that there were three ABCD1 variants in the proband, c.1047C>A, c.1415-1416delAG and c.1548G>A. The elder brother of the proband had the same three variants as the proband, but showed different clinical symptoms. The mother was the carrier of three variants. Multisite variants were uncovered in this family, which caused two different manifestations of adult-onset childhood cerebral ALD and adrenomyeloneuropathy.
PRINCIPAL CONCLUSION: These findings further increase our knowledge about ABCD1 mutations and the associated phenotypes, which is beneficial for the genetic counseling of patients with X-ALD.
